From 211710ca74adf790b46ab3867fcce8047b573cd1 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 29 Sep 2018 16:01:58 +0200 Subject: [PATCH] mac80211: fix setting IEEE80211_KEY_FLAG_RX_MGMT for AP mode keys key->sta is only valid after ieee80211_key_link, which is called later in this function. Because of that, the IEEE80211_KEY_FLAG_RX_MGMT is never set when management frame protection is enabled.
